The infographic is a comparison of the three latest in diesel engines.
Ford, Chevy and Dodge are the three engines that are being compared. Diesel engines need a lot of air to run. Therefore, the air intake systems are very important to a diesel engine. Ford engines have better air intake systems than the other two. Similarly, Dodge has a better displacement ratio as compared to the rest.
Chevy has the best towing capacity with the 5th wheel. Ford has the maximum torque while Chevy has the highest horsepower among the three.
Diesel engines are named after their inventor Rudolf Diesel and many of them are also capable of running entirely on bio-diesel such as vegetable oils.
